The Staff of Light was Takanuva's Toa Tool. Takua received it upon donning the Avohkii and becoming a Toa. It could channel Takanuva's power, and be used to play Kolhii. It was able to create flashes of light, a beam of concentrated light, and balls of light.

In BIONICLE: Mask of Light, the Staff of Light had its blade at a right angle to the shaft and a hammer on the other end, making it resemble a combination of a scythe and an enlarged Kolhii staff. In the set and comics, the blade was parallel to the shaft, making the staff resemble a "Lochaber axe", and there was no hammer end. In either case, the blade resembled an "unfolded" version of the head of the Chronicler's Staff that Takua originally carried.

In Bionicle: The Game, the staff gave Takanuva a glide ability and had unlimited energy.
